RFQ Guide: Service Robot Operating Costs and Vendor Evidence
Compare service and cleaning robot offers using a common operating-cost scope, measured staff work and explicit support terms. Original editorial guidance for testing vendor evidence and assumptions.
Choose a common comparison basis
This original Zhilianhai editorial guide supports preparation of a service robot RFQ. It is not an issued invitation, price quotation or investment forecast. Set the task, operating zone, service hours and comparison period before collecting offers. Evaluate delivery and cleaning outcomes separately, even if both systems operate in the same building.
Ask every respondent to state its commercial model and included services. Compare the required operating outcome over the same period, while preserving differences between purchase, lease and subscription proposals.
Separate initial and recurring charges
Request itemized hardware, installation, mapping, training, infrastructure and integration costs. Then request software, connectivity, support, consumables, scheduled maintenance and expected replacement items on a common usage basis. Leave amounts blank until supported by a written offer and an explicit assumption.
The Bear Robotics FAQ notes that rental arrangements and warranty terms can vary. Obtain the actual regional contract scope, including exclusions, rather than treating a website's general service description as the agreement offered to this site.
One-time equipment and setup charges.
Recurring fees, usage limits and renewal assumptions.
Chargeable repairs, visits, transport and replacement equipment.
Removal, return conditions and data access at contract end.
Count the work around the robot
Ask who prepares the area, loads trays, replenishes consumables, responds to faults and closes the shift. Include staff time for these activities in the comparison. Request the supplier's assumptions and verify them during a trial using a simple task log.
Kärcher's KIRA B 50 product information identifies an optional water-handling and charging station. Confirm whether an offered cleaning configuration includes this infrastructure and which tasks still require staff. Account for facilities work and servicing of the station where relevant.
Make performance evidence comparable
Request the exact model and configuration behind each claim. The Servi Plus specification distinguishes per-tray loading from total capacity. For a delivery offer, test the actual container arrangement and route rather than assuming maximum capacity represents every useful trip.
For cleaning, define the acceptable result, inspection method and manual finishing included in the measure. For delivery, define completed requests and the start and end of elapsed time. In both cases, record interventions and the operating conditions.
Manufacturer specification: identify its stated conditions.
Supplier estimate: request assumptions and calculation basis.
Reference deployment: explain task and site differences.
Local trial: retain observations, failures and configuration details.
Test the financial assumptions
Build a comparison using buyer-approved inputs for work volume, staffing and expected usage. Keep observed staff time separate from claimed cash savings. State whether released time supports other work, avoids extra hiring or changes scheduled labor; those are different business assumptions.
Ask for sensitivity cases with lower utilization, more interventions or longer downtime. Include a manual fallback and the cost of maintaining service during outages. Do not turn advertised battery duration or theoretical area coverage into guaranteed daily output.
Request an auditable response package
Require a configuration list, cost schedule, assumptions register, support terms, evidence references and proposed acceptance plan. Assign owners to unresolved facilities, network and staffing questions. Update the comparison when a supplier changes scope instead of carrying forward an obsolete total.
